TPS92210: working in CV mode

Part Number: TPS92210

Hello!

Tell me please, can I use TPS92210 in constant voltage mode? I want use it as PFC+Flyback at primary, with a number of Buck drivers at secondary side. I need use constant-on-time or peak current limit mode, to implement high power factor? Which way is better?

Hi Egor,

Yes, you can use TPS92210 in CV mode. If you configure the device to operate in DCM with constant on-time, you can achieve a power factor close to unity.

Hi Alex,

I did not mean to link you to this thread (apologies if I did by mistake). I messaged you a design guide for UCC28070. It explains the compensation a bit more clearly.
